microfine cement grinding machine

MicroFine Cement

MicroCem is a Portland cement based grouting material composed of microfine particles with a specific surface area of >800m²/kg. As a grout, it has excellent permeability, strength and durability properties. In use for grouting, the microfine cement is commonly batch-mixed with water and a dispersant or in a two-component mix with sodium silicate in the second tank.

Development of microfine cement grouts by pulverizing ordinary cements

Each ordinary cement was pulverized to produce three additional cements with nominal maximum grain sizes ( dmax) of 40 μm, 20 μm and 10 μm. A special laboratory mill, based on dry grinding with colliding air jets and equipped with a high-speed separator, was used to pulverize the cements. Table 1.Running on an 11-amp universal AC/DC motor, the DeWalt DWE46153 concrete grinder can spin its grinding disc at a speed of up to 11,000 ROM during load-free sessions. Moreover, the DeWalt DWE46153 concrete Best Concrete Grinders ( 2021 Reviews ) ToolsPros

Investigation on fundamental properties of microfine cement and cement

Based on the criteria for good injectability N = D 15 /G 85 > 15 [3], the average D 15 of the medium sand is 0.5–0.7 mm, the average G 85 of microfine cement (MC) is approximately 10 μm, and the average G 85 of ordinary Portland cement (OPC) is approximately 50 μm. Generally, the N 1 for OPC is approximately 10–14 (<15) and the Groutability Estimation of Grouting Processes with Microfine Cements Using an Evolutionary Instance-Based Learning Approach.
